HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 361,912, dated April 26, 1887.

Application filed November 24, 1886. Serial No.219,811. (No model.)

To @ZZ whom it may concern:

.Be it known that I, JOHN H. WILLIAMS, a citizen of the United States of America, residing at Council Grove, in the county of Morris and State of Kansas, have invented certain new and useful Improvements in Hay-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany- 'ing ing drawings, and to letters or figures of refer ence marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in baling-presses; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed ont in the claims.

In the accompanying` drawings, which illustrate my invention, Figure 1 is a side elevation of a baling-press embodying my improvements. Fig. 2 is a horizontal section thereof, taken on line m x, Fig. l. Fig. 3 is a vertical section on-line y y, Fig. 2. Fig. 4 is a transverse section on line .e e, Fig. l, lookingtoward the front. Fig. 5 is a transverse section on line w w, Fig. l. Fig. 6 is a detail perspective illustrating the clutches and shifting mechanism. Fig. 7 is a detail perspective of the follower.

A stout frame is provided, consisting of four longitudinal beams, A, braced together at suitable points by cross-beams, as shown. At the forward end of the frame I arrange two parallel beamaac, their ends being firmly secured to the end brace-beams, A. Between these parallel beams a a are secured bearings for the driving-shaft B and reversing-shaft B', and as these shafts are constantly connected by the gear-wheel and pinion b b', I prefer that these bearings be formed in a single block or cast- The shafts B B are arranged parallel with each other, their inner ends being mounted in bearin'gs formed in or secured toa cross-beam, A, just forward of the feeding-chamber C. This feeding-chamber C is closed at the sides and bottom, the top remaining open, except at the rear or discharge end, where a throat-plate,F,

is hinged to the forward end ofthe upper wall e, of the baling-chambcr E, said plate being held normally in line with said wall e by a spring or springs, f, secured to the frame. The bottom wall, e', of the baling-ohamber is pivoted at its forward or inner end to the frame-beams A of the press, and at the discharge end is connected with adjusting-bolts E', the upper threaded ends of which project through openings in a fixed part of the press, and are tted with nuts f', by the proper manipulation of which the outer end of wall e may be raised or lowered to decrease or increase the area of the baling-ehamber at the discharge end.

The main or driving shaft B is arranged centrally with respect to the sides of the pressframe, and a beveled pinion, I, is mounted to revolve freely, but not move longitudinally thereon. The hub of this pinion I is provided at one end with a sprocket-wheel, J, and at the other end with a clutch member, 7c, the teeth of which are inclined and adapted to engage oppositely-inclined teeth formed in the end of a sliding collar, L, splined to said shaft. The reversing-shaft B is also provided with a loose sprocket-wheel, J, which is connected with the sprocket .I on shaft B by a chain, j, and secured rigidly to the hub of this sprocket J is a clutch member, N', the teeth of which are inclined reversely to the teeth on clutch member k, and are arranged to engage with clutch-teeth formed on the end of another sliding collar, N, splined to shaft B.

Spiral or other springs l are arranged to constantly press the clutch members on collars L and N toward their mating clutch members, k and N, and these collars are provided with peripheral grooves Z n2, to engage studs m, projecting from a large lever, M, at points equidistant from its fulernm. This lever M is fulcrumed midway between the shafts B and B on a rigid bracket, M', secured to the frame, and is provided at its inner end with a short rearwardly-extending arm, m, arranged to lie in the path of a stud, O, iXed to the back of the follower D.

Pivot-ed in ears d', secured to the beams a a, at the front of the frame, are arms H H, carrying at their outer ends sectors provided on their adjacent faces with teeth h h', arranged IOO to mesh with teeth of pinion I; and pivoted to o the outer ends of these sectors are connectingrods G G', the other ends of these connectingrods being pivoted in ears d, secured to the back of the follower D. Above and below the -sectors, and in a vertical plane with the pinion I, are journaled guide-rolls t' fi, their journais being arranged in line, respectively, with the pivots of sectors H H', and the smooth outer faces of these sectors travel in contact With these rolls, whereby the toothed inner faces are maintained in mesh with pinion I at the expense of but little friction. The bearings in which the journals of these rollers are mounted may be carried by-diagonal or other cross-barst, secured to the press-frame.

At the Ycommencement of the operation of baling the parts will be in the position shown in Figs. 2 and 3-that is, the sectors will be at the outermost limit of their motion, the follower withdrawn from the feeding-chamber, and the driving-clutch members k L in engagement. The shaft B, revolving` in the direction of the arrow, Figs. 2 and 4, owing to the engagement of the driving-clutch, will actuatc pinion I and draw the sectors inward, thus straightening the limbs of the toggles H G and H G and moving the follower forward to force hay or other material into the baling-chamber. When the follower reaches its limit of forward movement, the connecting rod G will be brought in contact with thearmm of lever M, and'shift said lever to disengage the drivingclutch and throw the members N N of the reversing-clutch'into engagement. As the 1ever or sliding sleeves may become clogged or worn, however, and so fail to act, I have provided lever-M with a stud, m', with which the cam-shaped end a of a spring, n, engages, the arrangement being such that as the stud m passes the apex of the cam a the pressure of the spring a will be exerted to complete the shifting movement of the lever in either direction. The reversing clutch, operating through the sprockets J J and chain j, will cause the pinion I to rotate in a direction opposite to that of the shaft B, on which it is mounted, and so reverse the movement of the sectors H H and withdraw the follower to receive another charge of hay. As the follower approaches its limit of withdrawal, the stud O will be brought in contact with the arm m of lever M, and again shift said lever to disengage the members of the reversing clutch and throw the members of the driving-clutch in engagement to cause the advance of the follower. As the pinion b is much smaller than the gear-wheel b, which drives it, it follows that while the follower is actuated by the reversing-shaft B it will move much faster than when impelled forward by the shaft B, thus effecting a great saving of time. l

, In the operation of such machines difficulty has been experienced from the fact that part of a charge of hay will lodge on the follower and wedge between it and the forward end of the baling-chamber, thus often causing strain or breakage. By arranging the throat-plate F as shown, hay which may lodge on top of the follower will force the throat-plate F upward, thus relieving the parts from strain,and upon the withdrawal of the plunger the lodged hay will be thrown down into the feeding' chamber C by the action of the springs f,and be carried forward into the baling-chamber by thenext forward movement ofthe follower.

The degree of compression to which the hay is subjected in the formation of/a bale wlll be regulated vby the adjustment of the pivoted bottom e of the baling-chamber through the adjusting bolts and nuts E and f. The driving-shaft B will revolve continuously in one direction, the reversal of the movement of the follower being accomplished automatically by means of lever M and connecting parts, as hereinbefore explained.

I claiml. The combination, substantially as described, of the driving and reversing shafts geared together to revolve in opposite directions, and each carrying a loose sprocketwheel having a clutch member secured to its hub, a pinion secured to the driving-shaft sprocket, a chain connecting the sprockets, the follower, the pivoted toothed sectors and connecting-rods, sliding clutch-collars splined to the driving and reversing shafts, and means controlled by the follower for simultaneously shifting said collars at the end of each stroke.
